To all whom it may concern Be it known that "i, ROBERT A. GALLY, a. citizen oi the United States residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented cert-sin new and useful Improvements in Piano Autopleying Connections, of which the following is a specification The object of my invention is to secure compact, simple and noiseless connections. between an auto-playing action and the action of the piano in which both are com binecl.

Inthe drawings Figure 1 is a view from the bass end with the bass support or endtrunk removed to show the striker-pneuniatics and their fingers engaging the lugs on the piano action; Fig. 2 is front view of of piano action and lugs with player removed; Figs. 3 and 4 are upper and lower plans of e. striker-pneumatic and its finger and leveler; and Fig. 5 an end View of m0diiiecl use of the finger and regulator.

In previous structures verticalspace has been wasted in positioning the lugs 011 the abstracts to be engaged by the player, and the leveling devices cumbersome 01" out of easy reach.

In the present structuie the playerfingers 1 set on lugs on the piano action obstructs, these lugs being preferably arranges in severel rows one above the other, and the upset one as high as possible to allow ample vertical space for eliicient player action. These lugs are preferably made of metal in the form now shown, With attaching part 2 enii screws 3 below the engaging part 4;. The upper part is preferably slanted up and forward to aid inserting player. These lugs are staggered from one abstract to another sccoroliug to the number of rows of chests and stnlcer-pneumatics,three rows herein shown.

To avoid adding to the normal height of the piano abstracts, end. yet have sufficient height of top lugs to permit of effective size player action, the under part of front of Wippens 5 are cut away to clear the up per part of the top row of lugs These lugs at the top of the abstracts may be for every abstract if it is preferrecl to have one line and have the lower stiikei"pnemnetics connect to such top lugs by stickers es in this allowing it shorter stroke of Specification of Letters Patent.

the strikes than if the stickers attacked. wippen.

A sharp noise is often heal-(l from the sudden pull of the air on the cloth 3 of the striker-'pneuicoetic 7, especially when repeating a note s s-high speed incl power so the load of the piano action cloes not rr'eturn as quickly as does the striker-pneumatic. ellowing the over quick following of the pneumatic to be too sudden anal snap its cover cloth because of insufficient resistsiice to its new stint. present stnilzecpnew metrics T have s spring finger 1 immediately connected with the moving part of the striker-pneumatic 8 relieving the initial shock and. taking up any lost motion or,

slack of the folds of the striher pneumstic '2.

This s gning has :i guard 01? stop 8 which prevents any undue extent oi? yield of the spring 6 241111 gives it solid; stroke at the end of a heavy blow.

To level and regulate the Contact of he striker-pneumatic T to the piano action, so that ell irregularities and lost motion are removecl, 9. very compact regulate? is employee, which. con be I com the front of the player sctiou v.o, ulthough'the acting of the pneumatic?) i eucl fingers I are at rear. This is done by sures;- or bend 9 cttechetl to e fixed. support at the rear and movies; end 10 of the pneumatic. but above the moving part, and passing ovm and! under the moving end 10 and song the iuoving'boarcl of the pneumatic 7 to e foiwercl position Where it is accessible fOZ'IGgHliltlOIl as the player is'in playing position in the piano.

A; fastener or regulator ll. is provitletl at the forward pert so that the strap can be adjusted. fo'rwarcl or back and thus raise or lower the moving-end 10 of the strikerpneumstic 7.

The port of the strap or band 9 at and near where it comes around the moving end 10 of the striker-pneumatic 7, must be flexible or yielcling, but the other portion not necessarily so.

Several things are shown n the drawings to aid in illustrating the p fesent invention. but not claimed he::ein,- but not Waived thereby; being subjects of separate applications. 7
